Title:
MULTIPLE WIRE CARD WIRING AND CARDING CYLINDER WITH SUCH A WIRING
Document Type and Number:
WIPO Patent Application WO/2010/016872
Kind Code:
A8
Abstract:
Card wiring (20) includes a first carding wire including (22) a number of rough, pointed, first teeth (23), and a second carding wire (24) having smooth, blunt teeth (25). The rough teeth include a rough surface having a first coefficient of friction, an attack angle, and a back angle. The smooth blunt teeth have a smooth surface including a second coefficient of friction, The first teeth are adjacent to and spaced apart from the second teeth. The first coefficient of friction is sufficiently greater than the second coefficient of friction so that, in use, a fiber engaged by the rough, pointed, first tooth and by the smooth, blunt second tooth will be held sufficiently longer by the first rough tooth so that the fiber will be pulled in a direction transverse to a direction of movement of a web engaged by the first and second carding wires. Three or more carding wires may be provided.
